NITED STATES ATENT VVILLIAM C. GILMER, OFOAKDALE, GALFORNIA.

SASH-CORD GUIDE.

PECIFICATION forming part of Letters Patent No. 296.830, dated April 15, 1884.

Application filed August 7, 1883.

To all whom it may concer;

Be itknown 'that I, VILLIAM C. GILMER, a. citizen of the United States, residing at Oakdale, in the County of Stanislaus and Sta-te of California, have invented certain new and useful Inprovements in'Vindow-Pulleys; and I hereby declare the following to bea full, clear, and exact description thereof.

My inventi on relates to a new and useful improvement in window or sash pulleys; and it consists in placing two sheaves in a suitable receptacle of a cylindrcal-shaped pulley-pieceone at each end-and providing the outside of the cylinder with screw threads and a groove or key-seat for the reception of a key, as will be more fully shown.

The object of mvinvention is to permit of screwing the cylinder containing the sheaves into the sash-treme, and of securing it froni turning when in position by inserting the key above mentioned into the grooveupou the outside of the cylinder.

Referring to the accompanying'drawings, Figure 1 is an end View. Fig. 2 is a side elevation. Fig. 3 is a sectional View through the line of Fig. l. 4

Let A represent the cylindrical policy-piece having a receptacle its entire length, at each end of wlich,secu'ed by transverse pivot-pins, is a sheave, B. The weight-Gerd U is passed through the receptacle, its ends dropping down over and below the sheaves B in posider tightly in its place.

tion for the hanging of a weight at one end (No model.)

and for fastening the other end to the window, as is custonary.

These holes b adnit of the reception of a forked screw-drive1',by means of which the cylinder A is screwed into thesash-franie into its position. The cylinderA is also provided With a longitucliual groove or key-seat, a, into which, after the cylinder is screwed into its position, a key is driven to secure the cylin- The cylinder A is thusvery easily placedin or removed from its position in the sashframe.

I am aware thatit is notnew to make screwthreads upon the outer side of a body for the purpose of screwing it into position nor to i lock a device of any kind in place by means of a key or wedge, and these I disclaim.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The cylindrical-shaped pulley-piece A, pro vided With screw-threads and longitudinal groove a on its outer surface, and holes b at one of its ends, in comhination with the sheaves B, carrying cord C, one at each end of the receptacle of the cylinder A,substantially as and for the purpose herein described.

In testimony whereof I affix my signature in presence of two witnesses.
